The Anas crecca, commonly known as the Eurasian teal, has a native region that spans across the Northern Hemisphere. It is found throughout Europe, Asia, and North America. This includes countries such as the United Kingdom, France, Germany, Russia, China, Japan, as well as parts of the United States and Canada.

Eurasian teals typically inhabit freshwater wetlands, including lakes, ponds, marshes, and river deltas. They prefer shallow waters with abundant aquatic vegetation. The climate within these habitats ranges from temperate to subarctic zones, and the species often seeks sheltered regions during breeding seasons.

As a dabbling duck, the Eurasian teal primarily feeds on a diet of aquatic plants, seeds, and invertebrates. This species plays a crucial role in its ecosystem by aiding in the control of aquatic plant growth and serving as prey for larger predators. Their migration patterns also contribute to nutrient cycling across different habitats during seasonal movements.
